Esposito’s group got to work collecting the spiders in vials and jars. Then they took their haul back to their campsite to examine. When they put a particularly large specimen—nearly the size of a person’s hand—under the microscope for a closer look, everyone gasped. The huge spider had no eyes. The scientists knew right away that they had discovered a species new to science.
Esposito studies arachnids, like spiders and scorpions. Since 2004, she has discovered more than 50 new species. When she’s not in the field, she helps manage the arachnid collection as a museum curator at the California Academy of Sciences. Esposito talked to Science World about these amazing eight-legged critters.
